Hello!

Hey, I have noticed that my mail is getting stalled for roughly 45 minutes or so. I've been looking at my Postfix/Dovecot logs and at the Dynu email control panel.. What I see are repeated messages like:

Mar 6 17:36:31 mailhost postfix/smtpd[29140]: connect from mx2.dynu.com[107.161.27.201]
Mar 6 17:36:31 mailhost postfix/smtpd[29140]: lost connection after CONNECT from mx2.dynu.com[107.161.27.201]
Mar 6 17:36:31 mailhost postfix/smtpd[29140]: disconnect from mx2.dynu.com[107.161.27.201] commands=0/0

And the mail continues to sit in the queue at your end. But then, magically, it will connect successfully and flush the queue. So, at SOME level, it's "working".. My mail used to be instantaneous, and OUTGOING is still very quick, it's just incoming that seems to be an issue..

I've turned up Dovecot logging verbosity, but all I can see is the "lost connection" error and for the life of me, cannot figure out what might be going wrong or why the connection might be dropping. I have made no updates at my end, and have been using you folks as my store and forward provider for years now..

Would you have any suggestions as to what might be happening here? I can see no obvious IP service issues at my end, I run a business class fixed IP to my mailhost and it's been working fine for many years.

My full setup is FreeBSD running Postfix/Dovecot.. Pretty straight forward.

Thanks for any thoughts you might have about what's going on here..

Sincerely,

Eric Timberlake
